Directions

Cook the taffy

  1. In a large pot, combine molasses and butter.

  2. Boil the mixture until it thickens, about 1-2 hours.

  3. Drop a small amount into cold water; if it hardens, it's ready.

  4. Stir in the vinegar and mix for 1-2 minutes.

Shape and cool

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Molasses
Provides the main sweetness, deep color, and the sugar base that sets into chewy taffy.
Butter
Adds fat that softens the texture and keeps the candy tender rather than hard.
Vinegar
Adds acidity that helps keep the sugars from crystallizing, giving a smoother, softer chew.

The step that matters

Testing the thickness in cold water. The candy's texture depends on how much water has boiled off. Stopping too early leaves taffy sticky and soft, while cooking too long makes it brittle. The cold-water drop shows when the sugar concentration is right.
